Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies ditert-butyl 2-(3-ethoxy-3-oxo-propyl)-2-methyl-piperazine-1,4-dicarboxylate (CAS 1092478-40-4), a certified reference material (molecular formula C20H36N2O6, MW 400.51 g/mol) for analytical method development and quality control.
Structurally, ditert-butyl 2-(3-ethoxy-3-oxo-propyl)-2-methyl-piperazine-1,4-dicarboxylate (C20H36N2O6) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 400.51 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
